Dirac1l has developed the theory of magnetic poles, where he pointed out a possibility of
quantization of charge and explained why such particles have never been observed so far …

IRAC'S result that eogo= hc/4x'where eo is the elementary electric point charge and gs the
elementary point magnetic pole may be obtained very simply from classical electrodynamics …

In this paper it is shown that Maxwell's theory of the electromagnetic field in vacuum can be
stated in a form closely parallel to Dirac's theory of the electron. The electromagnetic field is …

In the theory of the electromagnetic field without charges, the potentials are not fixed by the
field, but are subject to gauge transformations. The theory thus involves more dynamical …

If one supposes that a particle with a single magnetic pole can exist and that it interacts with
charged particles, the laws of quantum mechanics lead to the requirement that the electric …

A quantum field theory of magnetic and electric charge is constructed. It is verified to be
relativistically invariant in consequence of the charge quantization condition eg ℏ c= n, an …

Existing attempts to apply the quantum theory to the electromagnetic field are open to
serious objections. Above all, the time is treated differently from the space co-ordinates; the …

The quantum field theory of particles with both electric and magnetic charges is developed
as an obvious extension of Schwinger's quantum field theory of particles with either electric …

[en] Without any assumptions other than the theory of classical electrodynamics applied to
the problem of a charged particle interacting with the field of an electromagnetic plane wave …

Dirac's' theory of the electron starts out with the following premises:(a) The wave-
equationmust be linear in form,(b) the equation must satisfy the requirements of special …
